Trimmer potentiometers are devices commonly used to adjust small electrical circuitry for voltage, current or resistance. The PV36Y201A01B00 is a trimmer potentiometer with integrated circuitry. Its application field and working principle are briefly outlined in this article.

This trimmer potentiometer is suitable for general purpose applications, operating up to a maximum voltage of 250V AC (250VA); at the maximum power rating of 25 watts. It is commonly used for simple resistor-type circuits such as those used in common consumer products. It also provides position feedback in motor control systems.

The PV36Y201A01B00 is composed of an adjustable wiper and resistive element which are voltage divider. It is usually connected in an enclosed potentiometer package, and when it’s adjusted, the resistance value of the resistor element can be varied. The adjustment range (by adjusting the wiper) is from 0Ω to the maximum resistance value of the potentiometer. The adjustment is operated manually by a fixing nut on the adjusting screw or by a drive. By doing this, any portion of the circuit output voltage can be adjusted as desired.

The device has a few working operations divided in 4 phases:

• OFF/ON Position: In this condition, the resistor arm is biased to one extreme position. Thus, it can be used as a simple ON/OFF switch with full value of resistance.
• OFF Position: This condition is achieved when the resistor arm is set at the other extreme position. Thus, it can be used as a simple disconnection switch with no electrical conduction.
• Scaling: In this position, the wiper of the adjuster screw is adjusted, setting a desirable resistance value. This phase is the usual utilization of the trimmer, since the circuit voltage is adjusted exactly as desired.
• Automatic Scaling: In this position, a voltage or a current applied to the potentiometer will regulate its position and set a desirable resistance. This application is suitable for automated systems, such as motor control.

In conclusion, the PV36Y201A01B00 trimmer potentiometer is a useful device for simple resistive circuits, as well as for providing position feedback for motor control systems. This device offers four working operations: OFF/ON, OFF, scaling and automatic scaling. The simplicity of its design allows easy installation and maintenance, and its adjustable wiper and resistor elements make the trimmer very versatile and suitable for many applications.
